Is there such a thing as being a nice jerk?

My observations on women have been that all the nice guys get shafted, while all the jerks get any woman they want. So, what I'm trying to figure out is if it is possible to be a nice guy, yet also be a jerk? Well, I can't seem reconcile it, because to be honest, in my opinion, they're totally opposite each other. I will admit that when I was in college, I tried being a jerk for a while and I went out on tons of dates, but the moment I went back to being a nice guy, I was dateless. So, if I were to combine the two, maybe I could find my balance. Who knows....
